look up any word, like dirty sanchez:
 
1.
When a women is crouching/squatting in the tub naked facing the faucet with it running. She then repeadetly catches water in her hands and hand over hand begins tossing it into her vagina in hopes to extract male sperm (cum) out of her. The motion similar to that of a monkey throwing there feces hand over hand over there shoulders. (Yet in the situations one hand at a time and into there vagina)
Male: Hey hunny I hear the shower running. Coming in to join you. hehehe

Female: (not responding/did not hear)

Male: (sneaks in and sees her in tub) Um hey...

Female: GET OUT OF HERE!!

Male: Did I just catch you doing a Monkey Douche
